You can have your house built fast, cheap, or well. Pick two; or a bit of all three that adds up to the same effort required. You can't have all three.
You can't have a language with 100% of the possible runtime perf, 100% of the possible compile speed and 100% of the possible programmer ease-of-use.
At best you can abuse the law of diminishing returns aka the 80-20 rule, but that's not easy to balance and you run the risk of creating a language that's okay at everything, but without any strong selling points, like the stellar runtime performance Rust is known for.
So a better way to think about it is: Given Rust's numerous benefits, is having subpar compilation time really that big of a deal?

As someone who uses Rust as a daily driver at work at zed.dev (about 600K LoC of Rust), and Zig outside of work on roc-lang.org (which was about 300K LoC of Rust before we decided to rewrite it in Zig, in significant part because of Rust's compilation speed), yes - it is an absolutely huge deal.
I like a lot of things about Rust, but its build times are my biggest pain point.
